The human body is approximately 60 percent fluids. During spaceflight, these fluids shift to the upper body and move across blood vessel and cell membranes differently than they normally do on Earth. One of the goals of the Fluid Shifts investigation, launching to the International Space Station this spring, is to test the relationship between those fluid shifts and a pattern NASA calls visual impairment and intracranial pressure syndrome, or VIIP. It involves changes in vision and the structure of the eyes and indirect signs of increased pressure in the brain, and investigators say more than half of American astronauts have experienced it during long spaceflights.

Recent research contributes to the effort to determine the nature of dark matter, one of the most important mysteries in physics. As indirect evidence provided by its gravitational effects, dark matter amounts to more than 80% of the universe.

"Star Wars" is about to get the LEGO treatment. Disney XD is planning to air "LEGO Star Wars: Droid Tales" later in 2015, according to a report from the Hollywood Reporter. The five-episode series will act as a re-telling of the six "Star Wars" films from

Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's "suburbs." It is located where astronomers have never spotted such a small cluster of stars before.

Several days after Rosetta's close flyby of comet 67P/Churyumov-Gerasimenko on 14 February 2015, images taken on this day by OSIRIS, the scientific imaging system on board, have now been downlinked to Earth. With a resolution of 11 centimeters per pixel, these data from OSIRIS' Narrow Angle Camera reveal highly detailed structures on the comet's surface. Since at closest approach Sun, spacecraft and comet were almost perfectly aligned, few shadows are visible in the images. With one exception: as a side-effect of this exceptional observational geometry Rosetta's shadow on the surface can be seen surrounded by a bright halo-like region.
